JavaScript - Trying To Fix A Firefox Extension - Linky. Help Is Very Needed.
Hello.
I have used the Firefox extension Linky for a very long time, it is one of my most used extensions bar none. However, one of the most attractive features of it broke somewhere in the updating from Firefox 3-4, as far as i know. I didn't find out about it until recently, due to never bothering to update past Firefox 3 until just a little while ago. This feature was the 'Select already visited links' option, which also works in reverse, letting you unselect all links to pages you've already visited. (Or rather, have listed in your browser history) Now, i am a complete noob when it comes to JavaScript, and i have very little knowledge about this type of programming, so i have no chance to fix this myself. This, is the reason i came here. I hope someone will be able to take a quick look at this code, and maybe tell me how to fix it, or make a workaround, or something. I really want to get it working again. I am almost certain that the problem lies in this section of the code: Code: LinkySelect.prototype.checkVisited = function() {
var gGlobalHistory = opener.Components.classes["@mozilla.org/browser/global-history;1"].getService(Components.interfaces.nsIGlobalHistory);
var cbox = this.getChecked(document.getElementById("cvbox"));
var selectlinks = document.getElementById("selectlinks");
var last = selectlinks.getRowCount();
for (var i = 0; i < last; i++) {
var tmp = selectlinks.getItemAtIndex(i);
if (gGlobalHistory.isVisited(tmp.getAttribute("value"))) {
tmp.setAttribute("checked", this.setChecked(cbox));
}
}
this.updateInfo();
}
Also, the Error Console reports this; Code: Error: opener.Components.classes['@mozilla.org/browser/global-history;1'] is undefined Source File: chrome://linky/content/select-links.js Line: 28 I hope that will tell someone something. I almost feels like it tells me something, but it's been years and years since i last tried to study this type of programming. Any help with this is appreciated. Thanks in advance for your time.

First off I apologize If this is in the wrong section of this forum. So I got this concept that I think Is pretty cool. I dont know If there's anything like It out there, If there is, let me know. This is the concept: You click the icon and down pops a map in which there's a circle (like this: imgur: the simple image sharer) You can resize the circle and move it around. Underneath the map there's a box where you can type your search. Let's say you search for "puppies" in Brooklyn, New York The idea is that It'll scan all the coordinates inside the circle and search for photos in google images containing those coordinates in the GPS info (EXIF).This can be useful If you for example wants to search for photos taken in your city, or even in your neighborhood. I can see many uses for this. The thing is, I don't know any programming languages so I can't do this myself. I don't even know where to start. I'm looking for a kind soul to help me with this, I don't have any money so I'm not looking to pay anyone to do this for me. I just want some help getting started, or if someone would be kind enough to do It for free. (Though that Is very unlikely.) Thanks in advance! Sorry for my bad english, it is not my native language.

I have a piece of code for adding categories to a shopping site, which was working fine but now doesn't submit after I made changes to try to validate the type image chosen for that category. I'll post the original and then changed code, anyone think they can see why it's not running? Code: function checkCategoryForm()
{
with (window.document.frmCategory) {
if (isEmpty(catName, 'Enter category name')) {
return;
} else if (isEmpty(catDescription, 'Enter category description')) {
return;
} else {
submit();
}
}
}
Code: function getFileExtension(filename)
{
var ext = /^.+\.([^.]+)$/.exec(filename);
return ext == null ? "" : ext[1];
}
function checkCategoryForm()
{
with (window.document.frmCategory) {
if (isEmpty(catName, 'Enter category name')) {
return;
} else if (isEmpty(catDescription, 'Enter category description')) {
return;
} else {
if (getFileExtension(fileImage) = '.jpg' || '.jpeg' || '.png' || '.gif' ){
submit();
} else {
alert("Enter this image format is not allowed, only .jpg, .png or .gif");
return;

Thanks! I want to download text file generated in a textarea here my download.php file code structure goes : <?php if(empty($_POST['filename']) || empty($_POST['content'])){ exit; } $filename = preg_replace('/[^a-z0-9\-\_\.]/i','',$_POST['filename']); header("Cache-Control: "); header("Content-type: text/plain"); header('Content-Disposition: attachment; filename="'.$filename.'"'); echo $_POST['content']; ?> and the javascript used (function($){ $.generateFile = function(options){ options = options || {}; if(!options.script || !options.filename || !options.content){ throw new Error("Please enter all the required config options!"); } var iframe = $('<iframe>',{ width:1, height:1, frameborder:0, css:{ display:'none' } }).appendTo('body'); and the script.js $(document).ready(function(){ $('#download').click(function(e){ $.generateFile({ filename : 'export.txt', content : $('textarea').val(), script : 'download.php' }); e.preventDefault(); }); by these assets i created a web page consisting a TEXTAREA , by entering some text on the textarea and clicking on the download button , a text files is generated and downloaded on the user's system, I packed the source code as a CRX file to use it as a CHROME extension, but while using the extension,the files are'nt generated, while the webpage works absolutely fine !!! Hi, I'm creating an extension on Firefox that wishes to parse the source of a page that the user is currently viewing for specific information. I've gotten as far as creating a simple extension with a button and when I click on it, it will show the url of the page I am currently viewing through: content.location.href All the examples I've seen so far concerning viewing the source forces you to either use the 'view-source:' convention or the 'xmlhttprequest' method. But these examples seems to be meant to be called within a web page and not an extension. When I cut and paste with these examples, I only get the source for the actual chrome portion of Firefox. I've tried modifying some of the examples to include 'content.document....etc' to reference what's being displayed in the browser, but it doesn't seem to work. Can anyone provide sample or reference code so I can extract the page source of my current window from an extension? Thanks! The mounds of RegExp data will take me days to sift through can someone help me create a regular expression to find a file extension? (all characters after a period) I have already gotten this far: .+\. to find everything before and including the period; and I was hoping to integrate the caret to say everything but .+\. But I just can't get it to work... Note: I will be writing a file to the server with JScript ASP. The file name will be passed to the script that writes the file, and I want to make sure that in addition to removing any possible code from the line being written, that I also prevent an executable file from being created. I will be searching for certain extensions and returning if anything else is found. Hi, I am kinda new to java scripting and here is what i am trying to do.

I just cant get it.... Hello guys i really need your help please. i need a code that when a button or image is clicked then a div's width and height are changed. Ive managed to get a few codes that does this, but the real problem is that, the contents of the div is an embedded flash file and i thought that by setting the flash width and height to 100% then the flash would fit to the new size of the div, but it just didnt work. I need a code that when a button is clicked then the div's and the flash's width and height are changed. please have a look at the temp website (http://latinunit.net/temp/ , you will understand where im coming from. on the right hand side i have a flash chat in a div , div is controled by a script that allows it to follow the scrollers up and down. My goal is to add a little button in the same div that says expand or maximise so when clicked the the div expands aswell as the flash file. i have spent 2 days on this little issue i just cant make it work, so please anyone can help me.
